One Panel #57-62: All the Way to Action Comics #1

A bit of film noir... Larry Steele is the kind of hero who will shoot a mobster while he's driving and worry about the hostage caught up in the ensuing accident later.

From The Adventures of Steve Conrad: "The Revenge of Devachan: Part 10" by Creig Flessel, New Adventure Comics #25 (Apr 1938)Love in quicksand. If you can't tell her then, you'll never be able to tell her.

Siegel & Shuster were about to unleash their prototypical superhero creation on the world, but in their other strips, they were already creating supervillains worthy of a superhero world... like Mr. Death!

The Grand Comics Database proposes Flessel as possible artist on this strip, but I'm not sure I recognize his style there, and his stuff is usually prominently signed "FLESS". Posted for the amusing accidental homoeroticism.

Being a newsreel cameraman sure is exciting! And check out that creepy death's head created by the two pilots in the front seat!

From Superman by Siegel & Shuster, Action Comics #1 (June 1938)

I very nearly chose to troll you guys by including a panel of Zatara's first adventure instead of Superman's, but I can at least showcase something other than the iconic shots we've all committed to memory - the rocket leaving Krypton, the super-strong baby, lifting the car. Superman running on telephone wires as the crook he's holding screams in fear of being electrocuted? We don't talk about that nearly enough!

But it's here. The moment. A superhero is born, and from him will come many others, and whole universes in fact. It's just a question of how quickly it'll happen. That's what One Panel is going to track now.
